Boring a Deep Hole

That part isn't too long to just grab with a four jaw. Save the change of underwear for your boring adventures.

Doing it in the mill would require a larger boring head. If you tried doing it with a 1/2 bar and if you could find one long enough, it would probably sing like the church choir. A boring bar held in the lathe would be a lot more rigid.

Another option, just because there are many ways of doing this, would be to mount the block on a faceplate in the lathe. That would be even more rigid than a four jaw, and you could couterbalance it. Just a thought.

I've been wanting to get a 3" boring head for quite some time now so maybe this is the justification I need to finally pull the trigger. A 3" boring head takes 3/4" shanked boring bars thus reducing the choir decibels.
The faceplate idea is not a bad option also.

Thanks Tom!
